EDWARD EMIL GLAUSSICN, OF HARTFORD, CONNECTICUT, XSSIGNOR TO UNION PAPER BAG MACHINE COMPANY, OF PHILADELPHIA, PENNSYLVANIA.

PAPEB-BAG BIACHINE Specification of Letters Patent.

Patented June 15, 1909.

To all whom it may concern:

Be it known that I, EDWARD EMIL CLAUs- SEN, a citizen of the United States of America, and a resident of Hartford, in the county of Hartford and State of Connecticut, with a post-otiice address in the above lace, have invented certain new and usefu Improvements in Paper-Bag Machines, of which the following is a specification.

This invention relates to machinery for automatically manufacturing paper bags from tucked paper tubes, and, as herein shown and described, is especially adapted for manufacturing the bags known in commercc square bottom paper bags.

The object of this invention is to provide a machine that is reliable in its action for forming the most intricate art in the manufactu re of square bottomed paper bags, which is, the forming of the well known diamond preparatory to pasting, folding, and closing the two end flaps and thus completing the bag.

The embodiment of the invention shown has a series of oscillating arms each provided with two thin straight or folding edges which oscillate into operative position in such a manner that the four lines of the right angled inwardly projecting folds and. the four edges of the diamond are accurately formed. The arms are oscillated into the bottom forming end of the blank, in such a manner that one straight edge of each of the four arms enter between the tucks of the tube and the other straight edge of each arm enters into the mouth end of the tube, the upper arms are then rotated and the diamond completed. The arms are then withdrawn, paste applied and then the arms are slightly raised from the surface of the carrier and again oscillated toward each other whereby the rear end flap is folded.

In the accompanying drawings:-Figure 1 represents a side elevation drawn on a reduced scale, of my improved paper bag machine, the mechanism which form the tube being omitted as they are well known in the art. Fig. 2. is a side view of the blank carrier showing the mechanisms which convert the bellows-sided tube into the diamond. Fig. 3 is a sectional end elevation taken on the dash and dotted line 33 and looking in the direction indicated by the arrows on Fig. Fig. 4 is a sectional plan view on the line 44 on Fig. 2. Fig. 5 is a plan view on the broken line 55 on Fig. 6. Fig. 6 is a front sectional end elevation on line 66 on Fig. 2. Fig. 7 is a cross sectional end View of the blank carrier showing the pincers whereby the paper blank is held to the carrier. Figs. 8 and 9 are plan views of the top of the carrier showing the completed diamond formed blank clamped thereto. In Fig. 8 the diamond forming instrumentalities are inserted, whereas in Fig. 9 these instrumentalities are withdrawn from the blank. Figs. 10 and 11 are similar plan views but showing the dia mond forming instrumentalities turning over the rear end flap, Fig. 1.0 showing the partially turned flap Whereas in Fig. 11. the flap is completely folded over. Fig. 1.2 is a transverse sectional view on line 1212 looking in the direction of the arrows on Fig. 1, show ing the gearing of the conveyor. In. Figs. 13 to 19 I have shown a modification of my improved paper bag machine, Fig. 13 being a side elevation of the carrier, part of which is an outside view and the balance a section on line 1313 on Fig. 1.4. Fig. 14 is a transverse sectional elevation taken on the broken line 1414 onFig. 13. Fig. 15 is a sectional elevation taken on line 1515 on Fig. 13. Figs. 16 and 17 are plan views of the top of the carrier with the diamond folded blank in position, 16 showing the diamond folding instrumentalities inserted, and 17 showing the same withdrawn from the blank. Figs. 18 and 19 are plan views of the top of the carrier showing the diamond folding instrumentalities turning over the rear flap. Figs. 20 and 21 are respectively a plan and a side view of the carrier with the paper blank clamped thereto and representing the diamond instrumentalities in the forward position ready to enter into the blank, whereas in Figs. 22 and 23 the arms 186 have entered. into their inner position of adjustment and the arms 88 are just about to enter into the blank.

i The directions of the movements of parts I are shown by adjacent arrows, and the positions of the different folding instrumentalities are shown irrespective of the relations of the positions to the cams which move these instrumentalities, it being sufficient for the purpose of this description to say that the i cams are properly laid out and out to produce the operations of the folding instrumentalitics at the proper time and to the required extent.

Referring to the drawings my in'iproved paper bag machine consists of two side frames 22 and 23, suitably supported on a bed of well known construction, not shown, in which are cross wise journaled the pulley shaft 24, upon which is mounted the hand wheel 25, the gear 2 6 and the driving pulley 27, and whereby power is communicated to the machine in the direction ofthe arrow 28. The gear 26 meshes into the, 29 and sets the train of gearing 30, 31, 32, 33, 34 and 35 into motion. The gears 31, 35, 33 and 34 are mounted on shafts S6, 37, 38 and 39 respectively upon which are mounted the cutting off and drawing rolls of well known construction. The gear also engages the gear 40 whereby the train of gearing 41, 42, 43 and 44 (see Figs. 1 and 12) is rotated and those gears are TQSPCCtlVGly mounted on the shafts 45, 46 and 47. Clamped upon inwardly projecting hubs of the side frames and surrounding the shafts 46 are the arms 48, 49 journaled in which is the shaft 47 carrying the conveyor roll 50.

For the sake of clearness I have shown the gears 26, 29, so, 31, 32, 33, 35, 4o, 41, 42, 43, 44, 101, 102 and 193 in dash and dotted lines but they are to be understood as having teeth out around their peripheries.

The gear 29 mounted on the shaft 51 which is journaled for rotation in the direction of the arrow 52 in the stationary bushings 58 and 54 and carries securely fastened thereto the blank carrier 55 which is of cylindrical shape and arranged to support eight folding mechanisms all identical in construction, but a smaller or larger number of folding mechanisms can be provided if desired. As the bottom forming end of the paper blank advances toward the blank carrier the adjustable presser foot 56 carried on the shaft 45, forces the lower ply of the tube to the carrier and permits the pincers 57 and 58 to enter between the tucks of the blank and clasp the blank to the carrier. The pincers are pivoted on studs and have inwardly projecting arms upon which the springs 59 press and keep the same in a closed position. To open the same I have arranged the arms 60 and 61 on the shaft 62 journaled in the central web of the carrier and the arm 61 is jointe l to the connecting rod 63 which engages at its lower end the cam arm 64, pivoted on the stud 65, and carries a cam roll which engages the cam securely supported to the bushings 53, and as the carrier is rotated by its shaft 51 the pincers are opened. and closed at predetermined intervals.

The mechanisms that operate on the paper blank to fold the diamond will now be described. They consist of two parallel shafts 67 and 68, journaled radially in the carrier, ach of which carries an arm 69 provided with a linger 79, which l: prefer to call a straightedge, as the finger has a fold defining edge which is substantially straight, though it will be understood that this edge need not be absolutely straight. Below the surface of the carrier these shafts carry the arms 71 and 72 which are linked together by the link 74. Supported above the surface of the carrier by these arms are the straight edges 73. The shaft 67 carries at its lower end the cam arm 75 provided with a cam roll which engages the groove of the cam 76 which is held on the bushing 54. As the carrier is rotated the arms 69, 71 and 72 with their straight edges 79 and 73 are oscillated in and out of operative positions as shown in Figs. 8 and 9. It will be observed that the fold defining edges of the fingers or straight edges 7 O and 73 which are attached to the same shaft are parallel to each other and when in their operative position are 45 degrees with the central median line of the cylinder and form. respectively the folding edges for edges of the diamond and the edges against which. the inside triangular folds are formed.

Extending laterally to each side from the central web of the carrier are the hubs 77, into which are pinned the studs 78, supporting the brackets 79. Journaled at the outer ends in the brackets 79, are the shafts 80, having heads 81 on their inner ends and sector pinions 82 on their outer ends, meshing into the sectors 88, held on the shaft 84, journalcd in the brackets 7 9 and also a hub of the carrier. On one side of the machine the sector 83 is provided with a cam roll 85 which engages the cam 86 and whereby the shafts with their heads 81 are oscillated, the spring 87 always keeping the cam roll upon. the cam.

In the head 81. is pivoted the arm 88, provided with the two straight edges 89 and 90, which arm is reciprocated into and out of oieration by the link 91, attached to the sliding rod 92, having on the outer end the collar 93, engaged by the yoke 94, held on the rod 95, engaged by the arm 96, on the shaft 97, journaled in a projecting hub of the bracket 79 and carrying on the lower end the cam arm 98 having a cam roll engaging the groove of the cam 99 fixed on the stationary bushings 53 and 54.

The fold defining edges of the fingers or straight edges 89 as well as the fold defining edges of the fingers or straight edges 90 are at angles of substantially 90 degrees with one another when in their inoperative positions. The vertical distance between the fold defining edges of the fingers 89 and 90 is determined as follows: The elongation of the fold defining edge of the linger or straight edge 89 passes through the intersection of the 153 and heads 140 so as to clamp the tube to the carrier. T he arms 88 are at this period in the position indicated bf, the line a (see Fig. 13) and also Figs. 20 to inclusive and then the are oscillated into operative position so that the edges are thrust into the moutl'i end below the upper pl"; of the blank and the edges 89 go between the tucks by the action of the cams 99, rods and 92. The heads 81 are then rotated by the sectors 82, 83 and 88 and the diamond is formed as shown in Fig. 16. Previously the two rear clips 127 have been closed. on the blank by the action of the cam 133 and its spring 133. Vfhen the diamond form is completed the arms 136 and 88 are withdrawn to the positions shown in Fig. 17. Paste is then applied to the blank, and simultaneously the front clip 120 is opened and the blank creased, by the creaser blades 1.11 and 112 and the co-acting grooves 113 and 114 in the carrier. this time the arms 88 are again slightly raised from the surface of the blank and at the instant that the creaser blade 112 creases the blank against its cooperating groove 114 the rear flap is thrown upward allowing the arms 88 with their edges 90 to get back of the flaps (see Figs. 10 and 18) and turn the same down upon the bag. The diamond folding is then completed by the turning over of the front flap by the folder 115 and delivering the bag into the delive rolls of usual construction as above described.

From the foregoing description, the operation of the machine as illustrated in Figs. 1 to 12 incl sive, will be readily understood. It will be sufficient to note, that after the paper bag blank has been delivered onto the carrier, it is clasped and held to the carr'er by the pineers 57 and 58 entering between the tucks and which are caused to be opened and closed by the arnt1s 6tand 61, red 63, cam arm 64, cam 66 and springs 59, the arms 69 having been previously thrust forward to enter into the mouth of the bag and above the lower ply of the tube. The straight edges 73 are simultaneously carried into operative position entering between the tucks of the blank. As the carrier continues to rotate the arms 88 with their straight edges 89 and 90 are in their forward. position and are thrust into the bottom forming end in such a manner that the straight edges 89 enter between the tucks and the straight edges 90 enter into the mouth and below the upper ply of the blank, and when these arms have entered to the proper position they are rotated by the sectors 82, 83 and cam 86 thereby forming the diamond as clc. l shown in Fig. 5:. The diamond folding instrumentalities are then. withdrawn and the rear flap folded as previously described, and. then the front flap is folded over by the folder 115 or by any other well known mechanism which form no part of this invention.
